Expression and Characterization of Calcium Channel Alpha1 Subunits in Atrial Tissue
… (HVA) L-type and a low-voltage activated (LVA) T-type. The LVA calcium current is often associated with growth and nuclear division. In atrial tissue, the LVA calcium current demonstrates developmental regulation and is upregulated in response to Growth Hormone (GH) and insulin-like growth …

An investigation involving a comparison between the hydrolytic degradation of lovastatin and simvastatin using HPLC
… acid forms, namely lovastatin hydroxy acid (LVA) and simvastatin hydroxy acid (SVA). Both statins possess similar chemical structures and the only differences is the presence of a 2-methylbutryloxy side chain moiety for LV compared to SV that consists of a 2, 2-dimethylbutryloxy side chain. …

Insulin-Like Growth Factor-1 Regulation and Subunit Composition of Low-Voltage Activated Calcium Channels in Atrial Myocytes
To test whether the LVA Ca$\sp{2+}$ channel contains $\beta$ subunit, I studied the ability of an AS ON $(\rm\beta\sb{all})$ targeting a common sequence of all four $\beta$ subunits to modulate the LVA Ca$\sp{2+}$ current in atrial myocytes. Our data showed that LVA Ca$\sp{2+}$ channels were …

Molecular Characterization of the Regulatory Subunits of Voltage -Dependent Calcium Channels From Rat Heart
… in atrial myocytes, where IGF-1 also enhances LVA Ca2+ current density. Thus, the expression of cardiac LVA current stimulated by IGF-1 is probably regulated by the expression of alpha2delta-3. Multiple beta subunits and their splice variants are expressed in rat heart. My studies demonstrate …

Avaliação da relação entre polimorfismos dos genes beta-defensina e mbl2 e a predisposição à infecção pela Leishmania infantum chagasi em cães de Serra Talhada, Pernambuco
A Leishmaniose Visceral Americana (LVA) é uma doença infecciosa grave altamente letal se não tratada. A taxa de infecção de cães pela Leishmania infantum é considerada como um parâmetro importante no monitoramento epidemiológico da LVA, visto que esta doença é considerada pela Organização Mundial …

Effect of Nutrition and Management on Marbling Deposition, Carcass Value, and Profitability in Feedlot Cattle
… cattle. Diets were calculated to contain 2300 (LVA) or 7250 IU/kg (HVA). No treatment differences existed for MS across all trials. Serum ROL was greater among calf-fed heifers and steers fed HVA. Serum ROL and MS were not correlated. Dietary intakes of vitamin A at three times NRC …

Portfolio Liquidity Risk Management with Expected Shortfall Constraints
… on the liquidity adjustment valuation (LVA). Also, we suggest a quantitative indicator that scores market liquidity ranging from 0 to 1 (perfect liquidity) for a portfolio with possible liquidity constraints. The thesis consists of three major studies. In the first one, we compute LVA …

Calcium Channel Gamma(6) Subunits Are Unique Modulators of Low Voltage-Activated Calcium Current
… gamma4 and gamma7 on the low voltage-activated (LVA) calcium channels, Cav3.1 and Cav3.2, which are expressed in cardiac myocytes. We generated a bicistronic vector containing green fluorescent protein (GFP) and either the gamma6 long isofrom, the gamma6 short isoform, rat gamma4, or the recently …
